Additional Backup Information:

Austin Water’s wastewater collection system is fundamental for the conveyance of wastewater to its treatment plants. The wastewater collection system is a large and complex system, consisting of approximately 3,000 miles of wastewater mains and serving approximately one million customers. The Upper Harris Branch Wastewater Interceptor project will construct new wastewater lines that provide gravity relief to the Dessau Wastewater Treatment Plant and multiple lift stations in the Harris Branch basin, enhancing wastewater service to properties in the area. 

 

This amendment will provide funding for additional construction phase engineering services, specialty inspections, warranty, and close-out services for the Upper Harris Branch Wastewater Interceptor Phase 1 and additional engineering design services for Phase 2 of the project. 

 

The previous City Council authorization provided design, bid, construction, and warranty engineering services for Phases 1 and 2 of the Upper Harris Branch Wastewater Interceptor Project. 

 

If this contract is not approved, the wastewater system will be at risk for sanitary sewer overflows during wet weather events due to inflow and infiltration in the Harris Branch basin. In addition, costly upgrades may be required at the Dessau Wastewater Treatment Plant due to increased demand from surrounding customers.
